Direct-drive Negative Pressure Fan The Optimal Choice for Ventilation and Cooling
An exhaust fan with belt is a useful ventilation device with the following characteristics:
Construction and Design:
-
The fan typically has a sturdy metal casing that houses the fan blades and motor. The belt-driven mechanism consists of a belt that connects the motor to the fan impeller.
-
The fan blades are designed to be aerodynamic, ensuring efficient air movement. They are often made of durable materials such as steel or plastic to withstand continuous operation.

Function and Performance:
-
This type of exhaust fan is primarily used to remove stale air, odors, fumes, and excess heat from a space. It works by drawing in air from one side and expelling it to the outside through a duct or opening.
-
The belt drive system allows for a certain degree of flexibility in speed control. By adjusting the tension of the belt or using a variable speed controller, you can regulate the fan's airflow output to meet the specific ventilation needs of different environments.
